COPENHAGEN, Denmark (AP) — Swedish police say a tourist bus has skidded off the road and ended up in a ditch in southwestern Sweden, killing at least one person and injuring 9 seriously.

Police spokesman Peter Adlersson says the bus was en route to Copenhagen, Denmark, with Christmas shoppers on a one-day trip, when the accident happened east of Goteborg early Thursday.

It was not immediately clear what caused the bus with about 58 people onboard to crash.
